(Wiley-Blackwell, 2011)Nephroselmis clavistella D. G. Faria et S. Suda sp. nov. is collected from coastal sand samples from the eastern and western coasts of Okinawa-jima Island, Japan. The description of the cultured strains is based on light ... -
A technical and economic evaluation of supplemental feeding strategies for Nile tilapia (Oreochromis niloticus L.) reared in lake-based cages
(AquacultureHub Inc., 2022-03)Tilapia cage farming in eutrophic lakes uses low stocking densities since tilapias can thrive mainly on natural food or minimal supplementary feeding. For semi-intensive Nile tilapia cage culture, feeding strategies to ... -
Techniques on algae harvesting and preservation for use in culture and as larval food
(Elsevier, 1990)A method of algae harvesting and preservation was developed. Test algal species consisted of two diatoms: Chaetoceros calcitrans and Skeletonema costatum, and two flagellates: Tetraselmis chui and Isochrysis galbana. ... -
Temperature and size range for the transport of juvenile donkey's ear abalone Haliotis asinina Linne
(Blackwell Publishing, 2011)Live transport of hatchery-produced juvenile donkey's ear abalone Haliotis asinina Linne was examined to evaluate the effect of transportation on the survival of juvenile abalone. Simulated transport experiments were ... -
Temperature fluctuation, low salinity, water microflora: Risk factors for WSSV outbreaks in Penaeus monodon.
(Society of Israeli Aquaculture and Marine Biotechnology, 2011)White spot syndrome virus (WSSV) has been devastating the shrimp industry for almost a decade. This study compares water parameters, alkalinity, and microflora in three ponds on a farm on Negros Island (Philippines) during ... -
Temporal changes in innate immunity parameters, epinecidin gene expression, and mortality in orange-spotted grouper, Epinephelus coioides experimentally infected with a fish pathogen, Vibrio harveyi JML1
(Elsevier, 2017)Changes in innate immunity parameters and epinecidin mRNA transcript levels were examined to characterize the non-specific immune response of E. coioides to pathogenic V. harveyi JML1 isolated from affected cage-cultured ... -
Temporal variation in the incidence of seaweed health problems affecting farmed Kappaphycus striatus in relation to environmental conditions in shallow waters
(Springer, 2024-04-18)A fixed off-bottom Kappaphycus striatus var. sacol farm was monitored for 12 months (June 2019 to May 2020) and the monthly incidence of disease and pests was recorded. Meteorological information in situ, from the nearest ... -
Terrestrial leaf meals or freshwater aquatic fern as potential feed ingredients for farmed abalone Haliotis asinina (Linnaeus 1758)
(Blackwell Publishing, 2003)Three terrestrial leaf meals, Carica papaya, Leucaena leucocephala, Moringa oliefera and a freshwater aquatic fern, Azolla pinnata were evaluated as potential ingredients for farmed abalone diet. All diets were formulated ... -
Test of refined formulated feed for the grow-out culture of tropical abalone Haliotis asinina (Linnaeus 1758) in concrete land-based tanks
(National Shellfisheries Association, 2016)A refined formulated feed for the grow-out culture of tropical abalone Haliotis asinina was evaluated to assess its suitability for a shorter culture period (<8 mo). Refinement procedures focused on the application of ... -
Test of size-specific mass selection for Nile tilapia, Oreochromis niloticus L., cage farming in the Philippines
(John Wiley and Sons, 1999)One generation of mass selection based on the collimation procedure (early culling of large fry) was applied on Nile tilapia, Oreochromis niloticus L., in net cages set in Laguna de Bay, Philippines. The objective was to ... -
Testicular histology and serum steroid hormone profiles in hatchery-bred catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)Testicular development, gonadosomatic index (GSI), and related steroid hormones (testosterone or T, 11-ketotestosterone or 11-KT, 17α, 20β-dihydroxy-4-pregnen-3-one or DHP) in serum were monitored during an annual reproductive ... -
Threonine requirement of juvenile marine shrimp Penaeus monodon
(Elsevier, 1997)The threonine requirement was determined for juvenile marine shrimp. Penaeus monodon postlarvae, PL20, were stocked in 30-1 fiberglass tanks at ten shrimp per tank arranged in a completely randomized design with six ... -
Thyroid hormone surges during milkfish metamorphosis
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)Both thyroxine (T4) and triiodothyronine (T3) were detected in fertilized eggs and larvae of milkfish. The concentration of T4 was lower than that of T3 only in fertilized eggs ... -
Thyroid hormones promote early metamorphosis in grouper (Epinephelus coioides) larvae
(Academic Press, 1998)The response of grouper larvae to the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), was examined. Two-, 3-, and 4-week-old grouper larvae were reared in seawater containing either ... -
